Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical inspections.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Raise the vehicle using a hydraulic jack and secure it on jack stands.
2. Remove the front and rear wheels to access suspension components.
3. Check control arms, bushings, and struts for any wear or damage.
4. Replace any worn bushings or control arms with OEM parts.
5. Reassemble all components and torque bolts to manufacturer specifications (typically around 70-100 Nm for control arms).

3. Examine and Replace Drivetrain Components

Sub-steps:
1. Inspect CV joints for any tears in the rubber boots and signs of grease leakage.
2. If damaged, remove the axle using a socket set and replace with a new CV axle.
3. Check the differential and transmission mounts for wear; replace if necessary.
4. Make sure all fasteners are properly torqued (consult repair manual for specific torque values).

4. Check Exhaust System

Sub-steps:
1. Visually inspect the exhaust system for loose brackets or damaged hangers.
2. Tighten any loose bolts or replace damaged hangers.
3. Ensure the exhaust is secure and does not come into contact with other components.
